No problem with this. You're getting 2.5:1 on your call and you are not a 2:1 dog vs even the tightest range. He played it right if he's got a monster. And you played it fine. IMO, you'll get shoves over from worse, like TT or AJ to your backraise. Certainly getting shoves from AK/AQ vs similar opponents in my games. Let's be honest, you're at the top of your range for doing what you did. Dead money = snap.
